Turn the heat to medium, add the lime juice, and stir with the whisk until smooth.
Stirring constantly, heat until the mixture starts to boil.
Boil for about 2 minutes, then remove from the heat. Allow to cool completely.
Mix all ingredients together and press in the bottom of an 8x8 pan.

Cool completely and then break into bite sized pieces.
In a medium-sized bowl, stir the sugar and milk with a wire whisk until sugar has dissolved.
Add heavy whipping cream and mix well.
Pour into your ice cream maker and follow the manufacturer’s directions.
